From 948569b72a5daf62559df764f37d5dc39dc76ef7 Mon Sep 17 00:00:00 2001 From: Maya Nakamura Date: Sat, 27 Oct 2018 03:15:03 -0700 Subject: [PATCH] staging: rtlwifi: Remove function that only returns the second argument Because the odm_signal_scale_mapping function is only called to return the second argument, remove the unnecessary function and change the statements that call it, including removing unneeded braces and adding a blank line. Note that removing casts (u8 to s32 and back to u8) will not lose information because the value converted should be between 0 and 100.
